I've been involved with the project since its first months, and have been a
central figure in its growth from a hobby site to the world's richest source
of map data.

I led development of OSM's online editing software from 2007 to 2013, and founded
the project to build a new editor in 2012-13. I edited and launched the
switch2osm.org website providing advice for
companies switching to OpenStreetMap. I've served as a board member of the
OpenStreetMap Foundation; I give talks
about the project; and I continue to drive OpenStreetMap forward by
working on new features such as routing.
